Abstract: Methods, systems, and devices are described for wireless communication at a wireless communication device. A wireless communication device may receive a data frame and use it to estimate a residual channel length (RCL). The device may then modify a finite impulse response (FIR) filter based on the estimated RCL. For example, the device may add additional taps to the FIR filter. The device may continue to adjust the FIR filter until the RCL is at or near zero. In some cases, the wireless communication device may send an indication to the transmitting device to adjust an FIR filter based on the estimated RCL. In some cases, the length of a guard interval may also be adjusted based on the estimated RCL.

Abstract: Methods, systems, and devices are described for power conservation in a wireless communications system. In embodiments, power conservation may be achieved by adaptively controlling power modes of a wireless communication device, and implementing lower power modes with various modes of the device. According to one aspect, the mode of the device may be a beacon monitoring mode or a delivery traffic indication message (DTIM) mode. In such a mode, the device may receive a portion of a beacon in a first power mode. The device may transition to a second, different (e.g., higher) power mode using information contained in the received portion of the beacon as guidance.

Abstract: Methods, systems, and devices are described for power conservation in a wireless communications system. In embodiments, power conservation may be achieved by adaptively controlling power modes of a wireless communication device, using a modulation and coding scheme (MCS) value as a factor for guidance. According to one aspect, the device may be in a reception mode. While in a first power mode, the device may receive control information for incoming data that is being transmitted via a transmission frame. The control information may be located in a first portion of the frame with the data following in a second portion of the frame. The control information may include or otherwise indicate an MCS value corresponding to the MCS applied to the incoming data. Based on the MCS value, the device may be adaptively switched to a second power mode for receiving the incoming data.

Abstract: A method of saving power in a wireless network can include determining a plurality of stations associated with an AP. The AP can create station groups using group selection logic. Notably, the group selection logic is transparent to the plurality of stations. A plurality of TIMs can then be sent, each TIM allowing only one station group access to a channel during a predetermined time interval, such as a beacon interval. In another method, a station can determine its sleep duration based on at least one of first information from the TIM to generate random sleep duration, second information regarding previous operation of the station, and third information regarding a status of the station. The first, second, and third information can include the number of stations associated with the AP and having buffered data based on the TIM, historical collisions, and power status.
Abstract translation: 在无线网络中节省功率的方法可以包括确定与AP相关联的多个站。 AP可以使用组选择逻辑创建站组。 值得注意的是，组选择逻辑对于多个站是透明的。 然后可以发送多个TIM，每个TIM在预定时间间隔（例如信标间隔）期间仅允许一个站组访问信道。 在另一种方法中，站可以基于来自TIM的第一信息中的至少一个来确定其睡眠持续时间以产生随机睡眠持续时间，关于站的先前操作的第二信息以及关于站的状态的第三信息。 第一，第二和第三信息可以包括与AP相关联的站的数量，并且具有基于TIM，历史冲突和电力状态的缓冲数据。
